Nothing has value unless society deems it, and thus nothing can hold value without the demand. If the demand goes away, it’s just a cool looking rock. I have cool looking quartz on my desk from a recent hike, that is more valuable to myself but to others a waste. The same thing could happen to BTC, or even to USD, it’s all relative. The question might be, what will AI find valuable in the next 5-10 years? Who knows, it could be uranium for energy that tops it all. Only time will tell
